To a/ZZ whom, it may concern.-

Beit known that I, ARTHUR M. BURNHAM, a resident of Gardiner, in thecounty of Kennebec and State of Maine, have invented certain new anduseful Improvements in Mop- Wrin gers and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in mop-wringers, the obj ect ofthe invention being to provide a mop-wringer which shall be simple inconstruction, which can be conveniently and easily packed into a smallspace for shipment, which will be comparatively cheap to manufacture,and which will be strong and durable when in use.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side view of my improvedwringer. Fig. 2 is a sectional view. Fig. 3 is a plan view; and Fig. 4isa horizontal section, with the bucket shown in dotted lines. Fig. 5 isa side elevation opposite to that shown in Fig. 1. Fig. 6 is a detailview of the xed roller, its mountings, and the guides e. Fig. 7 a detailview of the movable roller and its mountings.

A represents a pail or bucket, and B my improved wringer. A piece ofmetal a (preferably steel or bond-iron) is bent between its ends to formthe rear base portion of the frame, and the respective ends arepreferably bent slightly toward each other, as shown at l 1, and thenmade to project forwardly parallel with each other a sufcient distance,as shown at 2 2, to form an extended bearing for the base and precludeany possibility of the bucket or pail tipping forward when the operatorsfoot is placed on the treadle. A cross-piece b is bent at its ends 3 3to form bearings against the side pieces 2 2 and is provided with holesin the ends 3 3, in alinement with holes in the pieces 2 2 to receiverivets or bolts 4 4, to secure said parts together. Arms 24 24 aresecured to the pieces 2 2 and provided with rearwardly-projecting teeth25 25, adapted to engage the bucket and prevent any forward, sidewise,or vertical movement thereof. yAn arm or lug 26 is pivota'lly attachedto the rear base portion and provided with a screw-threaded hole at itsupper end to receive a thumb-screw 28, provided with a conical end 29 toengage the bucket and prevent any rearward or vertical movement thereof.The bucket or pail is preferably provided with a metal plate 30 with ahole or holes 31 therein to receive the conical end of the screw 28. vItwill be seen that this plate 30 will prevent wear on the bucket due tothe forcing forward of the thumb-screw. The arm or lug 26 is pivotallyattached to said base, so that it can be'swung to one side when it isdesired to remove the bucket or pail.

Parallel uprights c c, provided with rearwardly extending arms 5 5 attheir lower ends, are secured to the base portion by means of bolts 6 6,passing through holes in said arms 5 and the base. The upper ends ofsaid 'uprights are made approximately the shape of an inverted U (orhook-shaped) and provided with inwardly-projecting lugs 7 7, to which across-piece 8 is secured by means of bolts 9 or other approved means. Aroller d is revolubly mounted in the bent upper ends of the uprights c,said roller preferably made of wood and provided at its ends with metalplates `or disks l0 l0, whereby to prevent wear on the roller. The endsof the roller are made convex in order to prevent parts of the mopbecoming entangled about the journals of the roller. Guides e e arepivoted to the lugs 7 7 so they can be swung toward each other andpartly under the roller to permit the insertion or withdrawal of thepail, and said guides are adapted to guide the mop between the rollersand prevent the mop becoming wound around or tangled on one of therollers.

UpWardly-extending arms or lugs f f are secured to the portion 1 of thebase by means of bolts or rivets 1l. The movable roller g is mounted ina frame l2, which is composed of a single piece of metal having itscross-bar bent between its ends to form a depression 13, in which theroller g is mounted. This roller is preferably provided with convex endsIOO for the purpose heretofore described in connection with thestationary roller.

The depending or upright portions 16 16 of the frame 12 are pivotallyconnected at their lower ends by means of bolts `17 17 to the portions 1of the base. ArmslS 18, secured to the uprights 16 of the frame 12, arepivoted on said bolts 17 and provided at their outer ends withinwardly-projecting lugs or shoulders 19 19. Links 2O 2O connect theuprights 16 16 and arms 18 18. A foot-lever h, composed, preferably, ofa single piece of spring metal and bent around the frame,is pivotallyconnected at its ends to the upper ends of lugs or armsffby means ofbolts 2l 21 and nuts 22 22, the pivoted supports of the footlever beingthus disposed immediately over the .pivotal support of the swingingframe to the base. The foot-lever is adapted to normally rest on thelugs Aor shoulders 19 19, whereby when the foot-lever is forced downwardit will force forward the movable roller g. Atreadle 23 of any approvedconstruction is secured to the foot-lever, preferably centrallybetweenits ends. A spring t', preferably of wire, is secured to one of thebolts 17 at one end and bent at its other end to bear against one ofsaid uprights 16, whereby to normally hold the movable roller away fromthe stationary roller, and when the movable roller is pushed forward andthe footleve`r released the spring 'i will serve to throw the movableroller back to its normal position.

As before stated, the frame is made of steel, and it will be observedthat the parts of the frame are so disposed and the movable parts soconstructed thereto that the strain will come edgewise on the material.

By making the foot-lever of spring metal suicient elasticity will beaorded to permit the mop to be drawn between the rollerswhen said mopgets uneven or knotty, without endangering the several parts of thewringer.

Various slight changes, might be made in the general form andarrangement of theseveral parts described without departing from theyspirit` and scope thereof, and hence I would have it understood that Idonot wish to limit myself to the precise construction set forth, butconsider myself at liberty to make 4such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a mop-wringer, the combination with a base, of a stationaryroller-frame secured to said base, a roller in said frame, lugs on saidbase, a movable roller-frame pivotally connected to said base, a rollerin said lastmentioned frame, arms pivotally connected with said base,links connecting said arms and movable roller-frame, and a foot-leverpivotally connected to said lugs and adapted to bear against said armsand move the movable roller-frame.
